I have a syringe that i stick through one of the holes in the top and squirt it down into the cap. I leave a few drops in the web too. They drink the drops in the web sometimes or it'll just evaporate. Or u can open the top and stick the syringe down in. My versi is the friendliest T i own. If you're at all worried just distract him with food then once hes munching carefully refill it lol trick them
